You can use the connections on the daughter board shown in the image to plug the strips, IMPORTANT IT MUST BE A 24V LED STRIP or you will fry the LEDs or even something worse, you will also need a 2 jst xh2.54 connectors.
You can use any led strips if you don't want to use the printer power.
The front bar has a small hole on the left to pass the wire to connect to the daughter board, the rear one has a gap to help whit this as well.
